Legend: glucose oxidase (GOx), highly porous gold (hPG), chitosan (chit), tetrathiafulvalene (TTF), glucose dehydrogenase (GDH), reduced nicotinamide adenine dinucleotide (NADH), glucose dehydrogenase dependent on pyrroloquinoline quinone (PQQ-GDH), phosphate buffer (PB), phosphate-buffered saline (PBS), printed circuit board (PCB), and screen-printed electrode (SPE). The sensitivity refers to the geometric area of the anode.
